About Micrograms
A microgram (µg or mcg) is one millionth of a gram (10⁻⁶ g). It is the standard dosing unit for potent medications and micronutrients: vitamin B12 recommended daily intake is 2.4 µg, folic acid supplements are 400 µg, and levothyroxine (thyroid medication) doses are typically 25-200 µg. Air quality standards measure fine particulate matter (PM2.5) in micrograms per cubic meter - the WHO guideline is 15 µg/m³ annual mean. A grain of sand weighs about 50-100 micrograms, and a single snowflake approximately 3 micrograms.
About Tolas
A tola is a traditional South Asian unit of mass equal to the weight of a silver rupee coin - approximately 11.664 grams. It was the standard unit for weighing gold and silver across India, Pakistan, Nepal, and Bangladesh for centuries, and remains actively used in gold jewellery markets throughout the subcontinent. Gold is routinely priced and bought in tolas at jewellers' shops (sarrafas) in India and Pakistan. A 10-tola gold bar (116.64 g) is the most popular retail gold bar size in South Asia and the Middle East.
